How to modify the file's modification time using touch in Linux

Rsync sometimes because the server time is wrong, you need to change the time of the file modification, you can use the Touch command to modify the file's modified time:

1 touch-c-m-t 201101110000 teadme.txt

Modified Readme.txt to January 11, 2011:00 Modified

If you modify files and directories in bulk, use the

1 find/home/www/site-exec touch-c-m-t 201101110000 {} \;

You can change all the files and directories under the/home/www/site to modify the time.

Note the spaces in the command above.

Touch [-ACDMT] File parameters:

-A: Modify access time only.

-C: Only time is modified, not files are created.

-D: You can follow the date later, or you can use the –date= "date or time"

-M: Modify Mtime only.

-T: can be followed by time, in the form [YYMMDDHHMM]

such as Touch-c-T 0906270730 file
